What is the difference between HDTV and digital TV?
meco031719 asked:
The way I understand it is HDTV is more popular in the US while digital TV is a buzzword in the UK (even though you hear the latter in the US). Digital TV, in the UK at least seems to take after the concept of a DVD where you have value added services such as interactive menus and never before seen videos. Am I correct?

HDTV is high definition television. It has more resolution (lines per inch) than standard television so it is able to render far more detail.
I subscribe to digital cable television, but I can’t get HDTV because I don’t have an HD capable television to receive it on.
So, no, HDTV and digital are NOT just two different names for the same thing.
The terms “Digital Television” (DTV) and “High Definition Television” (HDTV) are often used interchangeably, but they are NOT the same thing.
Digital Television refers to a TV signal that is transmitted digitally as opposed to an analog signal. Digital Television can be broadcast in several different formats. Of these formats, two are considered to be “high definition”. The term high definition implies that the resolution of the digital television signal is very high. For example, the 1080i standard is considered high definition and has a resolution approximately twice that of analog NTSC television.
All HDTV is digital, but not all Digital TV is HDTV.
The same bandwidth for digital TV broadcasting can either used to supply a video signal (or several) and other services, or can be used to transmit a single HDTV signal.
Although there are technically 18 different standards for digital TV broadcasting (all Digital TV tuners are required to decode all 18 standards), the practical application of DTV has come down to 3 standards. These standards are: 480p, 720p, and 1080i.
Wikipedia has a good explanation of the two…
